Nginx 更新靜態頁面 不生效

今天更新了一個用Nginx做反向代理的vue做前端的web應該。
發現更新完vue頁面之後，重啓nginx或者nginx重新加載，靜態頁面也沒有更新過來

舊的Nginx配置

這樣配置更新靜態頁面是有問題的

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
	    listen       80;
	    server_name  localhost;
	
	    #charset koi8-r;
	
	    #access_log  logs/host.access.log  main;
	    
	    location / {
		    root   D:/police/terminal-client; 
		    index  index.html index.htm;
		}
		
		location /api/ {
	    	proxy_pass      http://localhost:8888/;
            proxy_redirect  off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
	}
}

解決方法

1. Nginx配置nginx.conf 設置sendfile爲off（默認爲on）
2. 重啓Nginx
3. 右鍵點擊Chrome瀏覽器刷新健選擇“清空緩存並硬性重新加載”（對於Chrome瀏覽器這一步很關鍵，普通刷新也不會生效。其他瀏覽器如火狐，普通刷新就行）

改後Nginx配置

增加下面這貨
http{
     sendfile on;
}

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        off;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
	    listen       80;
	    server_name  localhost;
	
	    #charset koi8-r;
	
	    #access_log  logs/host.access.log  main;
	    
	    location / {
		    root   D:/police/terminal-client; 
		    index  index.html index.htm;
		}
		
		location /api/ {
	    	proxy_pass      http://localhost:8888/;
            proxy_redirect  off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
	}
}

Nginx sendfile配置

sendfile: 設置爲on表示啓動高效傳輸文件的模式。sendfile可以讓Nginx在傳輸文件時直接在磁盤和tcp socket之間傳輸數據。如果這個參數不開啓，會先在用戶空間（Nginx進程空間）申請一個buffer，用read函數把數據從磁盤讀到cache，再從cache讀取到用戶空間的buffer，再用write函數把數據從用戶空間的buffer寫入到內核的buffer，最後到tcp socket。開啓這個參數後可以讓數據不用經過用戶buffer。
